Observational StudyThe effect of antenatal anaesthetic consultation on maternal decision-making, anxiety level and risk perception in obese pregnant women.
Obese parturients are recognised as high risk and an antenatal anaesthetic consultation is recommended. The potential positive and negative effects of this consultation have not been investigated. This prospective observational study aimed to determine if antenatal anaesthetic consultation affects decisional conflict, anxiety scores or risk perception in obese women planning vaginal delivery. ⋯ Our results support the current practice of referral of obese parturients for anaesthetic consultation, but demonstrate that most women remain unaware of the risks of obesity in pregnancy despite anaesthetic consultation.

Relaxant effects of metoclopramide and magnesium sulfate on isolated pregnant myometrium: an in vitro study.
Metoclopramide and magnesium sulfate are extensively used agents in obstetrics. In this study, the relaxant properties of metoclopramide and magnesium sulfate on pregnant myometrium, together with the possible reversing influences of oxytocin and cabergoline (a dopamine D2 receptor agonist), were investigated. ⋯ Both magnesium sulfate and metoclopramide relaxed myometrial contractions, and exhibited different responses to subsequent oxytocin treatment. The relaxant mechanism of metoclopramide may be via blockade of dopamine D2 receptor, which requires further investigation.
